Converting to sbc would be very expensive since you need more than just the engines to do the conversion. You also need the exhaust y pipe, V8 flywheel covers, and the outdrives are most likely the wrong gear ratio for the sbc. Essentially, you'd be looking at complete drivetrain swaps, X Unless you've found a good deal on an old, fresh water only, boat with working twins and a rotted out hull, you're looking at big money to repower.

However, some people like projects, and money is no object Bondo Moderator Staff member.

The problem is finding parts like exhaust manifolds. The center to center spacing is the issue if converting to v-8's. The conversion itself is pretty straight forward, you can find the parts, and you can even change the drives to a , , You have to change the lower unit ratio to 1. If the spacing works it could be done. But if you need to fill the transom in and cut new openings, you're looking at a lot of work. A pair of OHC 4s would work, but might under power this boat.

The s were probably right at the border line anyway. The GM cu in inline 6 with the SBC flywheel covers could be made to work and you can stay with the same 1. But the exhaust is Port side so you'd have to go thru hull with the exhaust or modify an AQB Y-pipe and use the port side only.

Seeing that, tells me the boat is not viable for restoration. You can buy plenty of boats with bad motors and rotten hulls, why have you fallen inlove with this one?

If yours are in good shape, have good compression, and don't have rotted exhaust manifolds then run them till they drop.

The expensive bits are the exhaust manifold proper, and the circulatory pump. There are some parts that are made out of unobtanium, but for the most part those parts don't really break. The heads are prone to warping if they do. Joined May 27, Messages The boat needs a few jobs, before it's seaworthy. The engine runs fine and has fresh water cooling. Here in Europe, the AQ which is a B30 engine from the Volvo car was quite popular in the 70's. Many Scandinavian boats from that time has them.

Maybe because the engine is built here If the engine has not rusted away, it's a fine machine that will run for many years. The most expensive problem is the exhaust manifold. And there are only two options; secondhand or HGE. As far as I know, it's quite a thirsty engine.
